What causes the stem to be redish? Is this normal ...

@Faegrows for some reason the plants react to the spectrum of LED lighting and do this it seems also you don't need to feed them bloom nutes until they are actually flowering

lol 'streaks of RED' that is.. not read

Hi, Red or purple stems in cannabis can be a sign of stress, nutrient deficiency, pathogens, or simply genetics.

red/purple hues on the stem can be a few things but in this case I think its because you are using LED lights. that coloration occurs for me when I grow indoors and not as much outdoors. There are some strains that can have more colourful hues in their stems but its normal and not related to deficiencies. Sometimes the stems of the plant can get red/pink in the case of a phosphorus deficiency, but then the other symptoms are also reflected in the leaves.
